Castel Béranger

This wedding cake-white church rises visibly above the north part of Paris. The striking building, with its towers and white onion dome (83 m high), was built between 1875-1914 on the birthplace of La Commune, officially as an act of penitence for the sins committed during the civil war in which thousands of Communards were executed, as well as for the previous bloodshed of the 1870 Franco-Prussian war. A number of prominent businessmen put up the money, and a dizzying combination of architects worked to put together the mock Romano-Byzantine extravaganza. Consecration followed in 1919. The view over Paris from the dome and from the square before it (200 m above sea level) is unsurpassed, apart from that enjoyed at the Eiffel Tower (50 km on a clear day). For the athletic traveller there are stairs from several directions to the top of the hill; otherwise there is also a funicular which runs every few minutes during the daytime from Place St. Pierre. Follow the signs that say "Funiculaire De Montmartre". Beware that the guards don't like it if they catch you taking pictures inside and will even yell "No photo!" and chase you down if they see you with a camera. Be warned: along the lower steps leading up to church, groups of mostly young African men gather and reach toward you with a small string, offering to loop it round your finger. In case it happens, pull back your hand, brush them off and move on. They might claim that "This is for the church." In case your feel that things go sideways, raise your voice to get people's attention and ask them call the police.

The Museum of Mankind, accommodated in the Palais du Chaillot, is an anthropological museum covering the history of mankind and human societies.

A symbol of Paris and one of the most famous landmarks in the world. Built by Gustave Eiffel in 1887-1889, the tower was almost torn down in 1909 and only saved due to its use as a telegraphy antenna. The queues can be very long. The tower allows online reservations at its website. You can select a date and time frame. If you miss the time on your ticket, you have lost your money. The north, west, and east pillars have elevators that go to the first and second floors; the south pillar has stairs that can be climbed to the second floor. To reach the top floor, an additional elevator ride is required, and the wait for this can be very long as well. Disabled visitors are not allowed beyond the second floor due to safety concerns. Taking the Métro as far as Ecole Militiare and then strolling up the Champ de Mars is a lovely way to arrive at the tower. Another phenomenal approach is to exit the Metro at Trocadero and see the Eiffel Tower from the other side of the Ecole Militaire.

The house in which the famous French novelist Victor Hugo once lived.

If you were a city planner in one of the great cities of our Earth and you discovered that a railroad right-of-way had been abandoned and would never be used again what might you do? Perhaps if you knew your stuff you'd convert it into a 4 mile long park, about half of which is elevated above street level on the old rail viaduct. This long narrow park pretty much allows the visitor to walk in carfree bliss from Place de Bastille to the Bois de Vincennes.

a Roman Catholic church on the east side of the Place Saint-Sulpice within the rue Bonaparte, in the Luxembourg Quarter of the VIe arrondissement. At 113 metres long, 58 metres in width and 34 metres tall, it is only slightly smaller than Notre-Dame and thus the second largest church in the city. It is dedicated to Sulpitius the Pious. During the 18th century, an elaborate gnomon, the Gnomon of Saint-Sulpice, was constructed in the church. In front of the church itself is the magnificent Place Saint-Sulpice which contains the 'Fountain of the Four Bishops'. The church has a long-standing tradition of talented organists that dates back to the eighteenth century. In 1862, Aristide Cavaillé-Coll reconstructed and improved the existing organ built by François-Henri Clicquot. Though using many materials from Clicquot's French Classical organ, it is considered to be Cavaillé-Coll's magnum opus, featuring 102 speaking stops, and is perhaps the most impressive instrument of the romantic French symphonic-organ era. Its organists have also been renowned, starting with Nicolas Séjan in the 18th century, and continuing with Charles-Marie Widor (organist 1870-1933) and Marcel Dupré (organist 1934-1971), both great organists and composers of organ music. The current organists are 'titulaire' Daniel Roth (since 1985) and 'assistant titulaire' Sophie-Véronique Cauchefer-Choplin. In Saint-Sulpice Sunday organ recitals are held on a regular basis (Auditions du Dimanche, following the High Mass, usually from 11:30am till 12:05pm, during the subsequent mass, a visit of the organ loft is possible).

Its exhibits come from such diverse origins as ancient Egypt, classical Greece and the Roman Empire, medieval Europe, and Napoleonic France, but controversially including many items that were looted from their places of origin. Its most famous exhibit, of course, is Leonardo da Vinci's painting of the Mona Lisa (French: La Joconde, Italian: La Gioconda), generally to be found surrounded by hordes of camera-flashing tourists. The Louvre poses many of the same challenges to the visitor as Paris itself; overwhelming in size, crowded in high seasons, and much information available only in French. If you want to see everything in the Louvre, plan at least two full days. However, it is better to pick and choose, as the collection was assembled with an eye to completeness rather than quality. As of July 2019, due to intense crowding and reports of ticket fraud, entry now almost always requires a pre-booked timed ticket, even for holders of the Paris Museum Pass.

This charming museum is owned by the French Académie des Beaux-Arts. Its main collection areas, the result of several large donations, include: First Empire art and furnishings; illuminated manuscripts; and Impressionist art, including the largest Monet collection in the world and works by Renoir, Manet, Morisot, Caillebotte and Gauguin.

Considered one of the most colourful Parisian parks, a local favourite, the Parc Montsouris was opened in 1878, having been designed by Alphand for Baron Haussmann. A large man-made lake and waterfalls are surrounded by long stretches of gently sloping lawns. Bronze statues are to be found studding the grounds, amongst the 1,400 trees, including such exotic varieties as the giant sequoia and the ginkgo. The park is featured in the film Cléo de 5 à 7. It is popular among families (there are two playground areas for children) and students.

Try to visit the cabinet des Médailles.

A former fortress and royal residence at the edge of the city, alongside the Bois de Vincennes. Most of the building is open to public.

Built in 1625, the Hotel de Sully is an interesting house with some sculptures in a beautiful courtyard. The house features special exhibitions, so check listings when in Paris.

One of the best-known and most beautiful churches in Paris, in the guise of a Corinthian order classical temple. Construction started in 1764, although the church was not finally consecrated until 1845. The Madeleine has a lavish interior of marble and gold.

One of the most eye-popping sights of Paris, the catacombs represent a network of labyrinthine tunnels, first excavated in the Roman period, that now house the remains of over 6 million burials removed here from the various overcrowded cemeteries and charnel houses all over Paris in the late 18th and early 19th centuries. Well worth a visit: the atmosphere is suitably morbid and gloomy (without being too scary), the dark tunnels containing neatly stacked piles of skulls and long bones. There is a limit to the number of visitors allowed within the Catacombs at one time (200 persons). So, if you arrive just after opening, you must wait until someone exits, approximately 45–60 minutes, before anyone is admitted. Steep stairwell on the exit of the catacombs. Can be challenging for the elderly or the unfit. Tickets can be purchased online at a small premium (€29, includes audioguide), allows you pick a date&time and to skip the long line

17th century church.

Suspended above the train tracks this garden is surprisingly calm and chilled-out.

The Pasteur Museum is housed in the apartment where the great scientist spent the last 7 years of his life. Hardly touched since that time, the museum is full of personal memorabilia and scientific instruments. Pasteur is buried on the grounds in a flamboyant mosaic-decorated mausoleum. The museum was closed to individual visitors for security reasons after the 13th November 2015 Paris terrorist attacks.
